Shbobo Shnth patches and appreciation



nice topic!
i am really enjoying my shnth, have one for a few months now –
not going deep enough with programming yet, usually i am playing and studying patches i found on muffs…

got shlisp installed on a rpi3 with supercollider for changing patches/situations –
if someone wants to try/improve:
(not working with all patches, sometimes it hangs (the same using fish or sublimetxt)… :frowning: )

// shnth patch switcher; // create a monome
b=GRHToggle(a, 0@7, 16, 1); // a horizontal 16x1 toggle placed at row 8
b.action = { |view, value|
0, {“sudo shlisp /home/pi/shlsp/jin.txt”.unixCmd;},
1, {“sudo shlisp /home/pi/shlsp/sidrazzi.txt”.unixCmd;},
2, {“sudo shlisp /home/pi/shlsp/sidraxEMULATIONS.txt”.unixCmd;},

I guess I would’ve chosen “Studies” and each one of your posts could have been a thread (because these long threads make it hard to find individual posts/patches later). But regardless, so happy to see all this shnth love here! Gonna make some time this weekend to go through these in some detail.


i’ll have to study this thread when back from holidays (i actually have taken my shnth with me to help the flight seem shorter, but ran out of laptop battery fast).
I have this instrument for two weeks and only had a few hours to scratch the surface, but i already love the physical interaction with it.


Wait, do you mean you can run shlisp and generate sound on just an RPi without the shnth?


no - i use a rpi running shlisp to change patches /situations on shnth.


open call to you ciat-lonbarde cats :slightly_smiling_face:
plz post some ideas/interesting sounds
from this cool synth- thx


some shnth fun with steamchaser (as posted above)


+1000 for this awesome topic.

not a shnth owner, but definitely a peter blasser fanboy. i’m from baltimore and have thought his world is so cool for years, but never decided to jump in.


I’ve got a couple of Shnths back from when we brought him over for a workshop at my old school (the “conversation” between @tremblap and Peter at the start of that video make me crack up each and every time I hear it).

I’ve played with Shlisp in a few years, so not sure what new developments there have been, but after seeing the vid with Peter demoing the Shtar in the Mobenthy thread, I’ve reached out to Peter to see if it’s possible to have one ordered for a narrow window of time I’ll be in the US in a week or so. If it turns out to be possible, I’ll be redigging into Shlisp and seeing what that bad boy can do!


Love that video and dialog so much, hahah!


I want to like the shnth but I’m a little skeptical. How usable do you all find it? Do you feel like it’s playable as a standalone instrument or more as a tool for making surprising noises?


It really depends on your definition of “playable as a standalone instrument” as well as your personal motivation and determination to make the shnth meet that definition.

The sounds are defined by shlisp code and that code is up to you. The four pressure bars, the buttons, the LED, and the antennas, all work as described, and are quite sensitive input devices. So that part is covered. But sound generation is on you. If you are especially concerned about 12TET tuning or other more traditional western music concepts, you’re going to have to put in quite a bit more effort than if you aren’t.

For many ciat-lonbarde enthusiasts, “playable as a standalone instrument” and “tool for making surprising noises” does not contain a meaningful distinction.


Excellent description! I want to add that you can upload multiple patches and program transitions, this way you can advance through multiple patches and create your movements/live set that way. There’s this great patch in the inforumors patchpack by khzmhz which has 70 pages and acts like a live set. I would love to do a whole liveset on just a shnth one day. :smiley:

Anyone here using their shnth v2 as a stereo effect processor? Would love to see/build more patches for mangling external sound.


For many ciat-lonbarde enthusiasts, “playable as a standalone instrument” and “tool for making surprising noises” does not contain a meaningful distinction.

yeah, I get that… but clearly there’s a line somewhere, right? I feel like if I can’t develop a mental model of how an instrument works, I might as well be listening to an rng.


There isn’t necessarily one line that everybody shares, no. But my hunch? You probably wouldn’t enjoy the shnth all that much. But now I’m speaking for you, and I may be wrong!


Yeah, so my question is: which side of that line does it fall on for you? :slightly_smiling_face:


I see it as a playable instrument that would be absolutely hopeless in an environment where 12TET tuning is an expectation.

But I’ve also heard rumors that even 12TET is possible with enough elbow grease.


In the case of the shnth, the instrument works in the way you define it through the code you write for it. There are a number of different inputs - what they do is up to you. So in many ways you define your own mental model of the instrument and how this works within the physical parameters (bars/buttons) it gives you.
Paraphrasing @jasonw22’s initial response there I feel.

Let’s approach this a different way. What would you want to do musically with a shnth? What makes you feel it’s something that you might be interested in?


Sure, it’s a general purpose microcontroller, but the physical interface, the programming environment, and the ecosystem of existing patches all shape what’s going on.

I like the sounds I’ve seen here. Programming in a strange lisp environment appeals to me. I also like the aesthetics of the shnth and ciat-lonbarde in general. I don’t care much about 12-TET (but of course it’s sometimes convenient).

Not trying to interrogate y’all, just looking for subjective experiences.


guess i’m one of those who finds the question a little opaque or hard to fit. as in, i don’t know actually what a playable instrument is, if it isn’t a tool for making surprising noises. (saying this with a conservatory background in string performance.)

so, i have a shnth (a prototype, it has some physical quirks) and i find it to have a broad range of use cases. you can very simply set it up so that (say) one set of buttons are gates, one set are octave switches, barre-presses and the antennae modulate timbre, and each barre is a fixed base pitch. a straightforward gesture-sound mapping which, for some, might constitute a playable instrument.

or you can make rather complex self-generating or “random” textures of course. no doubt that the ecosystem encourages sort of exploratory and chaotic applications.

for tuning the num/denom paradigm lends itself well to just intonation, as well demonstrated in @wednesdayayay’s lovely vids above (thanks for those!)

and to me, i guess i find shnth/shlisp’s actual sound palette relatively limited, but not in an unpleasing way. it feels a bit nostalgic, like playing with csound in the 80s. i kinda wish there were more options for straightforward lowpass filtering.

thanks for the question, it has inspired me to dig the thing out of a crate and take it on the train with me.

that’s super interesting! i think probably anyone who plays music, makes instruments, studies music theory, conducts, engineers records, builds amps, &c, has some kind of analytical instinct in the presence of sound. but that can take all kinds of forms, and for myself its something to be, i dunno, selectively suppressed or engaged at will (ideally, not always easily.)

personally i’d find it totally hopeless to maintain a sufficiently detailed mental model of how all the instruments work in a given piece of music, in real time. and one aspect of the art of orchestration is about totally subverting or annihilating the possibility of such a model.

do you have similar reactions to, say, compositional structure, or electronic production techniques? like, you have to fully work out the structure or signal flow, or experience discomfort / chaos? (i have friends like this)

i remember my dad listening to a record i had just made. “what do you think?” “it’s great! there’s some intermodulation distortion around 800hz.”

that would be hard. shlisp opcodes are ARM assembly. i’ve long thought (and said on this forum a few times) that it would be a cool project for someone to emulate each opcode in C. then shlisp would be a portable system. i’m never gonna find the time.
